To all @07mm t may concern:

Be it known that l, BERNERD W. KELLY, a residing at Somerset, in the county of Pulaski and 4State of Kentucky, have invented new and useful Improvements in Crude-Oil Burners, of which the following is a specication.

r1`he invention relates to an oil burner, and more particularly to the class of crude oil burners.

The primary object of the invention is the provision of a burner of this character wherein the same can be placed within the fire chamber of a stove for the use of crude oil in the heating thereof, and thereby minimizing the expense of fuel, and at the same time deriving maximum heat.

Another object of the invention is the provisionoof a crude oil burner wherein the construction thereof is of novel form to assure the perfect working of the same with safety, and thus minimizing the possibility of explosion.

A further object of the invention is the provision of a burner of this character which is simple in construction, reliable and efficient in operation, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and' ointed out inthe claims hereunto appended? In the drawings Figure 1 is an elevation of a stove with the burner constructed in accordance with the invention applied.

Fig. 2 is an enlarged vertical sectional view through the fuel and air supply pipe.

Fig. 3 is an enlarged vertical sectional view through the exhaust flue from the re chamber of the stove. v

Fig. 4 is a side view of the burner.

. Fig. 5 is a sectionalview on the line 5 5 of Fig. l.

Fig. 6 is a sectional view on the line 6-6 of Fig. 1.

Similar reference characters indicate co1' respondin parts throughout the several views in t e drawings.

Referring to the drawin s in detail, A designates a stove, and B t e tire chamber therein, into which extends theburner hereinafter fully described.

The burner comprises an elbow pipe l0 forming an air conduit adapted for communication with the atmosphere, and in one stretch thereof is formed a fan casing 11 in which is arranged a rotary fan wheel 12 supported upon an axle 13 which is journaled in bearings 14: formed in opposite cheeks of the fan casing 11 centrally thereof. The casing l1 is provided in opposite sides with air intake openings 11a. In the other stretch of the pipe 10 is formed a 'valve casing 15 having an oil passage 16 therethrough which has its continuity leading through the`wall of the pipe 10, and one end thereof communicates with a crude oil supply pipe 17 which leads from an oil tank or reservoir 18 which is disposed at a point elevated above the lire chamber for the gravitation of the crude oil therefrom, although the crude oil can be subjected to pressure in the tank for the positive feeding of the same.

Formed in the valve casing, and intersecting the passage 16 therein is a needle valve seat 19 in which is ada ted to be engaged the needle valve 20 which works in a stuffing box 21 carried upon a cap 22 for the said valve casing, the said valve 20 being threaded in the cap, and has mounted on its outer end a hand wheel 23 so that it may be manually turned for the opening and closing of the needle valve, thereby regulating or shutting oli' the supply of oil through the passage 16 'to the burner.

Detachably bolted or otherwise secured to the end of the pipe 10 formed with the valve casing 15 is a delivery nozzle 24 forming the burner tip, and the bore of which is in alinement with the air conduit in the pipe 10 for the discharge of the air through the smaller end of the said nozzle while at one side of the bore and contained in the nozzle is an oil duct 25 which communicates With the passage 16 and opens into a discharge nipple 26 mounted interiorly of the said nozzle, and extending hush with the smaller end thereof. l

Formed on or securedto'the nozzle 24 at the under side thereof near the smallerend is a suspension hook 27 with which is detachably engaged the bail 28 of an oil.` pan or cup 29 adapted to receive a quantity of oil which when ignited serves as a pilot light for the lighting of the burner, the nozzle being extended within the fire chamber B of the stove A and is fastened in position in any suitablemanner.

Leading from the fire chamber B in the stove A is an exhaust iiue 30 having a fan casing 31 formed therein, in which is arranged a rotary fan wheel 32, the axle of which is journaled in opposite cheeks of the fan casing centrally thereof, and to this vaxle is fixed a pulley wheel 33 having trained thereon an endless band or cable 34, the same being' also trained over a pulley wheel 35 which is xed to the axle 13. The fans of the wheel 32 are curved as shown and are also transversely concaved on their front sides and closely approach the periphery of the casing 31 to cause the full power of the heated air and products of combustion toY be utilized in driving said fan. The products of combustion and the heat within the re chamber 'B exhaust through the flue 30 and act directly upon the fan wheel 32 therein to cause the rotation thereof, which in its turn drives the fan wheel 15 within the casing 1l in the pipe l0 so as to draw air therein from the atmosphere, which is delivered to the nozzle 24 for the proper combustion of the crude oil iiowing from the nipple 26 when ignited,-

the oil being lighted from the iame of the burning oil in the pan or cup 29 which is initially lighted for the starting 0f the burner. The iow of oil is regulated by the valve 20, and is also cut 0E from the burner thereby.

From the foregoing description, taken in connection with the accompanying drawings, the construction. and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is 15A crude oil burner comprising a pipe tary fan arranged within the fan casing,

draft operated means having connection with the fan wheel for driving the saine, and an oil pan carried by the nozzle at the tip thereof.

2. A crude oil burner comprising a pipe forming an air conduit having fan an valve casings formed therein, a valve Within the valve'casings, the said pipe being provided with an air passage leading through the valve casing, a nozzle connected with the pipe and having air and oil passages coinniunicating with the respective air conduit and oil passage in the said pipe, a discharge nipple arranged interiorly of the nozzle and communicating with the oil passage, a rotary fan arranged within the fan casing, draft operated means having connection with the fan wheel for driving the same, an oil pan carried by the nozzle at the tip thereof, and means for directing the draft from a fire chamber in which the nozzle is arranged to the draft operated means.

In testimony whereof I aiix my signature in presence of two witnesses.

BERNERD W. KELLY.
